Definitions
- micromirror arrays or micromirror actuators
- devices with movable micromirrors arranged in a matrix so-called micromirror arrays or micromirror actuators
- micromirror arrays are known, for example, from the documents DE 10 2013 208 446 A1, EP 0 877 272 A1 and WO 2010/049076 A2. Disclosures regarding suitable actuator devices for displacing the individual mirrors of a micromirror array, the micromirrors, are shown, for example, in DE 10 2013 206 529 Al, DE 10 2013 206 531 Al and DE 10 2015 204 874 Al.
- a microelectromechanical device an illumination optics comprising such a microelectromechanical device as well as an illumination system and a projection exposure system, each with a corresponding illumination optics, as well as a method for producing a microelectromechanical device according to the invention are proposed.
- a microelectromechanical device comprising a carrier substrate with a substrate surface and several ME MS modules is proposed (MEMS: microelectromechanical system).
- each of the several MEMS modules comprises one, preferably exactly one, ASIC layer with an ASIC layer front side and an ASIC layer back side opposite this ASIC layer front side, a base plate with a base plate front side and a base plate back side opposite this base plate front side and several microelectromechanical components with a component back.
- the microelectromechanical components do not have to be identical in structure and/or function, although this can be the case.
- the base plate is arranged on the front of the ASIC layer and the back of the base plate is materially connected to the front of the ASIC layer via electrical contacts. A material connection using soldering or preferably sintering or eutectic bonding is particularly suitable for this.
- Silver sintering paste for example, can be used as the sintering material.
- the several microelectromechanical components are further arranged on the front of the base plate and their component backs are connected to the front of the base plate.
- the electrical contacts between the base plate and the ASIC layer are at least partially, preferably all, covered by at least one protective frame arranged between the base plate and the ASIC layer, which can also be electrically conductive.
- An implementation with several protective frames in a MEMS module is conceivable, in which case each of these protective frames comprises a different part of the electrical contacts between the base plate and the ASIC layer, but preferably there is only exactly one protective frame per MEMS module .
- continuity of an ASIC layer means that all elements of the ASIC layer are mechanically connected to one another via the layer itself. Such a mechanical connection via the ASIC layer between two elements can take place through the elements themselves and/or through other elements of the layer, such as ASICs, wiring carriers, suitable connecting elements, filling materials and/or joining materials. In the case of a non-continuous ASIC layer, this layer has elements such as ASICS and/or interposers that are not mechanically connected to one another via the layer itself. The ASIC layer therefore has a gap. Electrical connections can be continued using the electrical contacts between the ASIC layer and the base plate.
- the carrier substrate serves overall as a component carrier and can include electrical connections, for example plated-through holes for passing electrical signals through from one surface of the carrier substrate to another surface of the carrier substrate.
- electrical connections for example plated-through holes for passing electrical signals through from one surface of the carrier substrate to another surface of the carrier substrate.
- the carrier substrate can, for example, consist essentially of a ceramic, for example an AhOs-based ceramic.
- Such a microelectromechanical device consequently divides its plurality of microelectromechanical components into individual groups, each of which includes several microelectromechanical components and are referred to as MEMS modules in the context of this invention.
- the multiple MEMS modules can, for example, each have exactly 2, 3, 4, 5, 6, 9, 12, 16, 20, 25, 30, 36, 42, 49, 56, 64, 72 or 81 of the multiple microelectromechanical components, whereby other numbers > 2 are also conceivable.
- the multiple microelectromechanical components can, for example, be arranged in a rectangular grid consisting of columns and rows, for example consisting of two columns and two rows, two columns and three rows, three columns and three rows, three columns and four rows, four columns and four rows, four columns and five rows, five columns and five rows, five columns and six rows, six columns and six rows, six columns and seven rows, seven columns and seven rows, seven columns and eight rows, eight columns and eight rows, eight columns , and nine rows or nine columns and nine rows.
- microelectromechanical devices according to the invention are in turn connected to form a higher-level unit, for example in order to cover larger areas than is practicable with a single microelectromechanical device according to the invention.
- the protective frames arranged according to the invention between the base plates and the ASIC layers ensure that no damage can occur in the areas surrounded by the protective frames.
- the structures of the ASICs located in these areas and the electrical contacts are protected from damage and contamination, as can occur during the production of a microelectromechanical device according to the invention and also during later operation.
- the protective frames serve to isolate you from the environment.
- the mechanical cohesion between ASIC layers and base plates is also increased.
- the protective frames of the MEMS modules are preferably designed in such a way that, in particular, temperature-related deformations of the MEMS modules are reduced.
- each of the several microelectromechanical components of each of the several MEMS modules has a substantially rectangular, preferably square or a substantially hexagonal base area.
- Essentially rectangular or hexagonal base area smaller deviations from a rectangular or hexagonal base area are conceivable, for example through rounded corners and/or indentations or bulges.
- it can also include several such micromirror arrays according to the invention, for example in order to implement a larger overall micromirror array with an arrangement of this large number of micromirror arrays, which makes it possible to redirect incident light beams with a larger beam diameter.
- Figure 1 shows a schematic representation of a part of an exemplary microelectromechanical device according to the invention in a side view
- Figure 3 shows in schematic form as a flow chart a method according to the invention for producing a microelectromechanical device.
- FIG. 1 shows a schematic representation of a part of an exemplary microelectromechanical device 110 according to the invention, a micromirror array, from the side.
- two MEMS modules 120 (left MEMS module: 120a, right MEMS module: 120b) are arranged on the substrate surface 100a of a carrier substrate 100, each of which includes several microelectromechanical components 130, four of which are shown in FIG .
- the microelectromechanical components 130 are micromirrors. These each include a mirror element 134, which in turn has a reflection surface 136 for reflecting light. These mirror elements 134 can be moved by displacement devices 132.
- the microelectromechanical components 130 are arranged on the front side 160a of a base plate 160.
- This base plate front side 160a is connected to the back sides 130b of the microelectromechanical components 130.
- two base plates 160 are visible, on which the four visible microelectromechanical components 130 are located.
- the microelectromechanical components 130 are connected to the ASICs of the respective ASIC layer 140 via electrical contacts 144.
- the ASICs of the ASIC layers 140 can in turn be connected to further electronics (not shown) via electrical contacts 146, which can be arranged on the carrier substrate 100, for example.
- silicon vias (TSV, through-silicon via) 142 can also exist in the ASIC layers 140, which can be used, for example, to produce electrical connections between such further electronics on the carrier substrate 100 and the microelectromechanical components 130.
- Such vias 142 can also be used, for example, using interposers can also be part of the ASIC layers 140, or can be implemented using the dies of the ASICs.
- FIG. 2 shows a schematic representation of a MEMS module 220 of a second exemplary microelectromechanical device 210 according to the invention in a side view in an upper partial figure and a schematic view of a sectional plane A to illustrate the arrangement of a protective frame 295 in the MEMS module 220 in a lower partial figure.
- the MEMS module 220 shown here also has four microelectromechanical components 230 that are visible in the side view of the upper part of the figure.
- the MEMS module 220 shown has, as can be seen from the lower part of the figure, 16 microelectromechanical components 230, each with one Displacement device 232 for displacing mirror elements 234 with reflection surfaces.
- electrical contacts 244a, 244b, 244c, 244d which are partial continuations of electrical connections such as vias 142 in the ASIC layer 240. At least some of these electrical contacts 244a, 244b, 244c, 244d are surrounded by a protective frame 295. Preferably and as shown in Figure 2, all electrical contacts 244a, 244b, 244c, 244d are located within the area defined by the protective frame 295.
